Opinion

UNITED STATES DISTRICT COURT MIDDLE DISTRICT OF FLORIDA TAMPA DIVISION

MICHAEL SUTHERLAND, and COMFY MATERIALS LLC,

Plaintiffs,

v. Case No. 8:24-cv-00854-WFJ-NHA

WELLSHOW MACHINING PARTS, INC.,

Defendant. _____________________________________/

ORDER Before the Court is Defendant Wellshow Machining Parts, Inc.’s (“Defendant”) motion for summary judgment (Dkt. 61) regarding Plaintiffs Michael Sutherland and Comfy Materials LLC’s (“Plaintiffs”) amended complaint (Dkt. 17), as well as Plaintiffs’ motion for summary judgment (Dkt. 58) regarding Defendant’s amended counterclaim (Dkt. 45). The parties have filed their respective responses (Dkts. 65, 66) and replies (Dkts. 69, 70), and further submitted supplemental briefings (Dkts. 74, 75). Upon careful consideration of the filings and arguments, the Court grants in part and denies in part Defendant’s motion for summary judgment, and grants Plaintiffs’ motion for summary judgment. BACKGROUND1 The parties are vendors, primarily online, of materials including filament for

3D printing. This case arises from Defendant’s sale of such products via online distribution partners, including Amazon. Dkt. 47 ¶¶ 7, 8. These products each included certain descriptions in their listings. Dkt. 17 ¶ 17; Dkt. 45 ¶¶ 12–16.

Plaintiffs provide an incomplete screenshot of an alleged Amazon listing by Defendant from March 23, 2024. Dkt. 17-2. While the title of this listing is obscured in this screenshot, the description reads as follows: ●【Food Safe】Wellshow PETG Filament is lab certified in compliance with 21CFR 177.2420.

●【Wide Compatibility】Compatible with most of the FDM 3D Printers such as BAMBU P1P, X1C, P1S, A1 mini, Comgrow Creality Ender, ANYCUBIC, Creality 3D, etc. Works in AMS(Automatic Material System)

●【Better fluidity+clog free】Good fluidity enables PLA+(PRO) filament to be extruded evenly and smoothly during printing.

●【Better toughness】Enhanced version of PLA+(PRO) filament ensures smoother and better toughness. Toughened and hard to break, better elongation at break

●【Anytime Service】Whenever you encounter any printing issues, Wellshow will assist you to achieve perfect printing.

1 The following is a summary consisting of facts that are not in dispute. Although some of the facts the Court finds undisputed may be nominally contested, mere speculation or conjecture does not create a genuine dispute. See Cordoba v. Dillard’s, Inc., 419 F.3d 1169, 1181 (11th Cir. 2005). Those facts which are merely alleged are labeled as such. Id. Plaintiffs further allege that there were “sixty (60) or more Amazon listings for Defendant Wellshow’s products” at issue, “including . . . PETG and PLA filament

products.” Dkt. 17 ¶ 17. No further information regarding the “sixty (60) or more Amazon listings” is provided by Plaintiffs. Id. Because all further instances referenced by Plaintiffs relate back to the sole initial screenshot, the language of this

listing will be used for the Court’s ensuing analyses. See, e.g., Dkt. 64 ¶ 9; Dkt. 65 at 7; Dkt. 74 at 4, 11. Plaintiffs registered a copyright with the U.S. Copyright Office for a certain work (the “Work”) entitled “Certified Food Grade PETG 3D Printer Filament -

CARBON by Comfy Materials - Lab Tested FDA Compliant Food Safe, 1.75mm, 1kg, Accuracy: +/- 0.02” under Registration Number TX 9-379-454 on March 29, 2024. Dkt. 17-1; Dkt. 61 at 1; Dkt. 64-1. Plaintiffs provide the full text of the claimed

Work, which reads as follows: Certified Food Grade PETG 3D Printer Filament - CARBON by Comfy Materials - Lab Tested FDA Compliant Food Safe, 1.75mm, 1kg, Accuracy: +/- 0.02
